  • Publication number: 20220251605
    Abstract: The invention features methods for introducing a therapeutic cargo into a cell of a subject. Such methods include the steps of (a) contacting the cell with a purified human CSb-6 and the therapeutic cargo; and (b) contacting the cell with a purified C7, C8, and C9, thereby forming a membrane attack complex (MAC) in the membrane of the cell, facilitating entry of the therapeutic cargo into the cell. Still another method involves treating neovascularization in an eye of a subject, the method comprising the steps of (a) contacting choroidal blood vessels of the eye with a purified human CSb-6 and the therapeutic cargo; and (b) contacting the choroidal blood vessels with a purified C7, C8, and C9, thereby forming MACS in cells of the choroidal blood vessels, facilitating entry of the therapeutic cargo into the cells of the choroidal blood vessels for treating neovascularization.

  • Patent number: 10309973
    Abstract: The present invention provides compounds that are surrogates of post-translationally modified proteins and uses thereof. Numerous diseases are associated with post-translationally modified proteins that are difficult to obtain in homogenous form and in quantities needed for immunization and use as convenient standards, calibrators, and/or reference compounds that facilitate the detection and analysis of endogenous post-translationally modified proteins. The surrogate compounds of the invention typically comprise antigenic epitopes (one of which carries a post-translational modification) that are tethered by a flexible and hydrophilic linker. The resulting compound behaves like a surrogate of the post-translationally modified protein because it preserves the character of the included antigens and allows recognition by specific antibodies targeting the individual antigens.

  • Patent number: 9952200
    Abstract: A method for determining the translation initiation inhibitory potency of a composition having an unknown level of translation initiation inhibitory activity which comprises contacting an eI-F2?-WT cell with said composition for a time and at a temperature effective to inhibit proliferation of said cell, measuring the level of inhibition of proliferation of said eIF2?-WT cells induced by said sample and comparing the level of inhibition of proliferation induced by said sample with the level of inhibition of proliferation induced by a standard having a known amount of said activity, the amount of said translation initiation inhibitory activity in said sample being proportional to the level of inhibition of proliferation of said eIF2?-WT cell.
